3-6 | Heated Acid Gas Sample Probe (Large Diameter)
4. Connect the Sample and Vent Lines to the HAG Probe.
The Sample Line fitting is on the same side of the HAG Probe as the
Sample isolation valve (Red handle). The Vent Line fitting is on the
same side of the HAG Probe as the Vent isolation valve (Black handle).
Do not install the Insulating Jacket on the HAG Probe at this time.
This will be done after the analyzer and HAG Probe have been pow-
ered up and the Sample Probe fittings have been leak-checked (with no
leaks).
5. Connect the Sample and Vent Lines to the Sample Inlet/Outlet Fittings
on the analyzer:
Non-Shelter Installations:
Route the Sample Line to the analyzer and connect it to the Sample
Inlet fitting.
Route the Vent Line to the analyzer and connect it to the Vent Outlet
fitting.
Shelter Installations:
Route the Sample Line through the hole marked “Sample Line” on the
side of the shelter and connect it to the Sample Inlet fitting.
Route the Vent Line through the hole marked “Vent Line” on the side of
the shelter and connect it to the Vent Outlet fitting.
If the Sample and/or Vent Lines have extra length between the HAG
Probe and the analyzer, properly secure them to avoid any sags or
sharp bends (to prevent plugging).
6. Perform these procedures in the order listed to complete the installa-
tion and then return to this procedure:
a. Install the Aspirator Drive Gas Line (see “Connecting the Aspirator
Drive Gas Line”).
b. Optional: Install the Zero/Cal gas line as per the analyzer and/or
HAG Probe drawings. This line, which must be 316 stainless steel,
is supplied by the customer/end user (unless it is integrated in the
Sample Line).
